View CDN statistics in Grafana

With the Gcore cdn-stats plugin in Grafana, you can display the CDN statistics by:

• Total Traffic, which is total traffic volume, consisting of traffic from origin to CDN or Shielding + from Shielding to CDN + from CDN to users;
• Byte cache Hit Ratio, which is the share of cached traffic, calculated using the formula: 1-(traffic from the origin to the CDN or Shielding/traffic from the CDN to users);
• Edges Traffic, which is traffic from CDN, consisting of traffic from Shielding to CDN + from CDN to users;
• Shield Traffic, which is traffic from Shielding to CDN;
• Origin Traffic, which is traffic from the origin, consisting of traffic from the origin to the CDN or from the origin to the Shielding;
• Total Requests, which is the number of requests to the CDN;
• 2xx, 3xx, 4xx, 5xx Responses, which is the number of 2xx, 3xx, 4xx, and 5xx responses;
• Bandwidth, which is bandwidth, calculated based on traffic from the origin to the CDN or Shielding + from Shielding to CDN + from CDN to users;
• Cache Hit Ratio, which is the share of sending cached content, consisting of responses with cached content / requests to CDN;
• Shield traffic ratio is the efficiency of the Shielding: how much more traffic is sent from the Shielding than from the origin, calculated using the formula: (traffic from the Shielding to the CDN - traffic from the origin to the Shielding) / traffic from the Shielding to the CDN;

You can group metrics by the following parameters:

• Clients is for clients;
• Resource is for CDN resources;
• Region is for regions;
• Country is for countries;
• Data is for data centers;
• Vhost is for a personal domain.

Open the dashboard settings by clicking on the gear icon in the upper-right corner.

Go to the “Variables” section and click “Add variable”. You can use it to filter the data on the chart.

For example, to be able to filter resources, you need to make the following settings and click “Update”:

Go back to the dashboard by clicking the arrow icon in the upper-left corner of the screen.

Connect the variable with the Dashboard. To do this, specify its name in the “Resources” field of the “Filters (comma separated)” section.

Important! Enter ”$” before the variable name.

Now you can choose resource data to be displayed on the chart.

Save the Dashboard. To do this, click “Save” in the upper-right corner of the panel.
